Design and Fabrication of a Flexible and Self‐Supporting Supramolecular Film by Hierarchical Control of the Interaction between Hydrogen‐Bonded Sheet Assemblies

Abstract

A super film: 2D sheet assemblies of alkylsilylated deoxyguanosine derivatives were formed by double intertape hydrogen bonding between hydrogen-bonded 1D tape motifs. Introduction of polar oxyethylene units at the sheet surface allowed the fabrication of a flexible, self-supporting supramolecular film (see figure) with a well-defined structural hierarchy.
